IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 205,005, dated June 18,1878; application filed December 13, 1877.

To all whom it may concern:

Be it known that I, SAMUEL S. SPEAR, of South Weymouth, in the county ofNorfolk and State of Massachusetts, have invented an Improved InsideSash and Blind Holder, of which the following is a specification:

This invention relates to holders for sashes and blinds wherein the sashand blind are held in position by friction of a lever carried by thesash or blind, the lever operating against the casing.

The invention consists in a shouldered hand: lever adapted to movehorizontally, a connecting device, which operates to release afriction-lever which is pressed outward by a spring, the smooth surfaceof the friction-lever bearing against the window-frame, all ratchetsbeing dispensed away, as hereinafter more more fully described andclaimed.

Figure 1 represents awindow sash or blind, a sufficient portion beingbroken away to show my invention Fig. 2, the friction-lever Fig. 3, theconnecting-link; and Fig. 4, the hand-lever detached, to better showtheir exact construction. i

The window -frame a and sash or inside blind I) are and may be of anyusual construction.

The holding-lever c, pivoted to the sash or blind at 2, has afriction-face, d, which is projected by a strong spring, a, in thedirection of the arrow near it, far enough and with sufficient force tocause the friction-face d to engage a portion of the casing, over andagainst which the edge 3 of the sash or blind moves and bears hardenough to maintain the sash or blind in any position in which it isdesired to leave it.

The spring cl may be of any desired stiffness, and may be of any usualconstruction adapted to press the end d of the lever outward.

The lower end of the lever c is provided with an opening, 4, to receivethe hooked stud 5 of the link f, it having a forked end, 6, (see dottedlines, Fig. 1,) to extend under and within the recess 7 of thehand-lever g,havin g shoulders or corners 8, and being pivoted at h tothe sash. The spring 6, operating upon the friction-lever 0, will pressits end d outward and hold the sash stationary. At the same time thelower end of the friction-lever will be pressed inward, moving the linkf, so

that its forked ends 6 will rest against the shoulder 8 of the handlever, it remaining (shaped as in this instance of my invention)substantially in a horizontal position. Now, to move the friction-leverto cause it to release the casing and permit the sash to be moved, Iturn the hand-lever upon its fulcrum-pin h, and its shoulder 8, whetherthe lever be lifted or depressed, will act upon the end 6 of the linkand move it in the direction of the arrow on it, and consequently thelower end of the lever 0 will be moved outward.

The hooked stud 5 prevents the separation of the lever c and link,except when both are in straight line, the fulcrum of the lever c beingwithdrawn to place them in such line. The longitudinal movement of thelink f is not sufficient to drop its forked end from the portion 9 ofthe hand-lever, and its outer end is held up by the lever 0.

These devices are very efficient to hold the sash or blind in anydesired position, and the lever c is released by the action of the leverg as its knob t'is grasped to lift or push down the sash.

Pulling or pushing the lever 9 up or down as the sash is to be lifted ordepressed enables the person with one hand to easily manipulate thesash, and just as soon as the hand is removed from the knob the movementof the sash is stopped.

I claim- The shouldered hand-lever, friction-lever c, and spring 0, incombination with a connecting device, f, whereby, by the movement of thesash up or down, (a knob or projection, i, on the hand-lever beingseized for that purpose,) will simultaneously release thefriction-lever, and the release of the knob or projection willsimultaneouslype it the spring to operate the friction-lever to h 1d thesash in position, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

SAMUEL S. SPEAR.
